Winwdos Phone 从手机中读取相册图片

首先声明一个存图片的类:

public class FlowItem
    {
        public string Name { get; set; }
        public ImageSource Picture { get; set; }
        public ImageBrush BackupgroupPicture { get; set; }
    }

声明一个图片集合:

private ObservableCollection<FlowItem> _pictureList = new ObservableCollection<FlowItem>();

得到所有的图片:

void GetWP7Picture()
       {
           MediaLibrary library = new MediaLibrary();
           _pictureCollection = library.Pictures;

           if (_pictureCollection.Count == 0) return;


           foreach (Picture _p in _pictureCollection)
           {
               Stream _s = _p.GetImage();
               BitmapImage _bi = new BitmapImage();
               _bi.SetSource(_s);

               FlowItem _w = new FlowItem();
               _w.Picture = _bi;
               _w.Name = _p.Name;

               ImageBrush ib = new ImageBrush();
               ib.ImageSource = _bi;

               _w.BackupgroupPicture = ib;

               _pictureList.Add(_w);
           }
       }
